Before her Harry Potter series sold more than 450 million copies, won innumerable awards, was made into a hit movie franchise, and transformed Rowling's life, she lived in a cramped apartment with her daughter, jobless and penniless, and felt like the biggest failure she knew.

Rowling has said she received "loads" of rejections from book publishers when she first sent out her " Harry Potter and the Philosopher's Stone" manuscript, and she tweeted that she pinned her first rejection letter to her kitchen wall because it gave her something in common with her favorite writers. "I wasn't going to give up until every single publisher turned me down, but I often feared that would happen," she said.

Famous comedian Jerry Seinfeld suffered several setbacks before his big break

Though he had rehearsed his material thoroughly the night before, when he stepped out on stage, he couldn't remember a word of his act. "I stood there for about thirty seconds ... saying absolutely nothing, just standing there, freaking out. I just couldn't believe it."

After improving his stand-up act, the comedian earned a small role on the sitcom "Benson." But, according to the New York Times, Seinfeld and the show's producers clashed over the character's direction, and he was fired after only four episodes.

Unfortunately, no one bothered to tell Seinfeld he'd been cut, according to " Jerry Seinfeld: Much Ado About Nothing." Seinfeld showed up for a read-through of the script one day and found there was no copy waiting for him. The assistant director pulled him aside and told him that they had neglected to inform him he was no longer on the show. Seinfeld was humiliated, but he went right back to performing at comedy clubs. After one performance, a talent scout for the "Tonight Show" was in the audience. Seinfeld landed a gig on the show and his career immediately took off.
